First off, you said you fixed swords and guns, but haven't touched bombs. I realize that charging is a pain, almost useless at lower levels. So why not make bomb charge faster or at least uninterruptible.
Next. You've added new ways to get damaged by status inflictions and decreased the damage from fire. I think this is good, however with the buffed weakness and resistance system, I think it would be wise that all damage from status inflictions would be turned into normal damage, thus fire is not only good against constructs and undead, but everyone else as well. so would shock, poison, freeze, and curse with their counterparts.
Also, you probably get this a lot, but some 2* materials are harder to find than 3* materials, sometimes even more than 4*. and some of these are essential to a great number of recipes. I like how there are new monsters, and even some new monster types like the robo spider thing and the laser knight things. hopefully, this in the future will allow better drops of certain items at the tiers people need them *hint hint swordstone*
